I was separated from the caravan when departing New Mexico........for Arizona. Now running behind the caravan the Border Patrol targeted me at the inspection station and directed me to pull over. I was approached by two agents who questioned me as. to "what do you have in the car"? ....I responded"Well personal baggage".....................they replied " NO.....What do you have under the hood?" I then had to give them a peek under the hood! Cool guys...they had never seen a ZL 550!
